在成都市大邑县西岭镇的飞水村，胸径2.4米、高35.8米的千年香果树在盛夏7月再次绽放出白中带绿的花瓣，散发出阵阵清香。这株被誉为“中国最美古树”之一的香果树，不仅吸引了周边居民和游客前来游玩与摄影，更是成都“古树医生”团队长期关注与保护的对象。
成都“古树医生”团队，由植物园的专家组成，涵盖生态学、园林、植物保护、园林植物与观赏园艺、土壤学等多个专业领域。他们自2014年起，已经连续10年为5000多棵古树名木进行了全面的健康检查，每棵古树都拥有专属的“体检档案”，确保每一棵古树都能得到科学、精准的保护。
“古树医生”的工作包含了对古树的全方位观察与记录，从长势、周围环境、寄生植物、病虫害等方面进行综合评估。通过专业的仪器，他们能够生成“树干横截面扫描像”，了解树干内部的完整性和腐朽程度，同时利用土壤养分速测仪测量土壤的氮磷钾含量及pH值，确保古树的生长环境适宜。最后，他们对古树名木的健康状况进行综合评估，并出具详细的“体检报告”。
此外，“古树医生”团队还承担着收集和保存古树种质资源的重任。对于数量不超过5株的珍稀树种，如香果树、珂楠树等，团队优先进行种质资源收集，目前已有500余份种质资源得以保存。这些珍贵的资源不仅有助于古树的繁育，还为成都林木资源的物种多样性提供了保障。
在成都这片孕育了9450余株古树名木的土地上，这些千年古木如同历史的守望者，见证了城市的发展与变迁。通过“古树医生”团队的精准治疗与科学保护，这些古树名木得以继续见证和记录着成都的未来。
“古树医生”团队的辛勤工作，不仅守护了古树名木的健康，也为成都乃至整个城市的生态文明建设注入了新的活力。在他们的努力下，这些千年古木将继续见证成都的繁荣与美丽，成为连接过去与未来的桥梁。

Title: “Ancient Tree Doctors in Chengdu: Guardians of the Health of Centuries-old Trees”
In the village of Feishu in Xiling Town, Deyi County, Chengdu, a 2.4-meter chest diameter and 35.8-meter tall centuries-old camphor tree, blooming with white and green petals in the July heat, exudes a sweet fragrance. This camphor tree, one of China’s most beautiful ancient trees, not only attracts local residents and tourists for leisure and photography, but is also a long-term focus and protection target of the Chengdu “Ancient Tree Doctor” team.
The Chengdu “Ancient Tree Doctor” team, composed of experts from the botanical garden, covers multiple fields including ecology, landscaping, plant protection, ornamental horticulture, and soil science. Since 2014, they have conducted comprehensive health checks for over 5,000 ancient trees and famous trees, each with a dedicated “health check file” to ensure that every ancient tree receives scientific and precise protection.
The “Ancient Tree Doctor” team’s work includes a comprehensive observation and documentation of the ancient trees, assessing their growth, surrounding environment, parasitic plants, and diseases and pests. They use professional equipment to generate “cross-sectional scans” of the tree trunks, understanding the integrity and degree of decay inside, and measuring the nitrogen, phosphorus, potassium content, and pH of the soil using a soil nutrient rapid tester, ensuring the growth environment is suitable for the ancient trees. Lastly, they assess the health status of the ancient trees and provide detailed “health check reports”.
Additionally, the team bears the responsibility of collecting and preserving the genetic resources of ancient trees. For rare tree species such as camphor trees and kinnaman trees, which have a population of less than 5, the team prioritizes collection of genetic resources. Currently, over 500 such resources have been preserved. These precious resources not only aid in the propagation of ancient trees but also ensure the biodiversity of forest resources in Chengdu.
On the land of Chengdu, which houses over 9,450 ancient trees, these centuries-old trees act as sentinels of history, witnessing the city’s development and transformation. Through the precise treatment and scientific protection of the “Ancient Tree Doctor” team, these ancient trees continue to witness and record Chengdu’s future.
The diligent work of the “Ancient Tree Doctor” team not only protects the health of ancient trees, but also infuses new vitality into Chengdu’s and the city’s overall ecological civilization construction. Under their efforts, these ancient trees will continue to witness the prosperity and beauty of Chengdu, serving as a bridge connecting the past and the future.
